Purpose: The purpose of this study was to construct a questionnaire to assess male workers' sobriety behavior based on Ajzen's Theory of Planned Behavior (TPB). Methods: A primary questionnaire with 56 questions was constructed based on literature review and structured interview with male workers. The Content Validity Index (CVI) was evaluated by a group of experts, construct validity was tested by principle component analysis, and reliability was evaluated by Cronbach's ${\alpha}$ and the test-retest reliability test. Results: Fifty two questions showed higher than .8 of CVI. Four factors explained 78.71% of the total variance among items for sobriety intention and direct measure, and six factors explained 67.99% of the total variance among indirect measure items and those factors coincided with the variables of TPB in factor analysis. Cronbach's ${\alpha}$ of this questionnaire was .873 and the result of test-retest reliabilty test was relatively reliable. A total of 41 items with 7-point scale were constructed in the final version. Conclusion: This questionnaire was valid and reliable to measure sobriety behavior based on TPB in male workers. It can be useful to evaluate the result of a sobriety program for male workers.

The primary goal of the study was to provide some preliminary validity evidence for the Vocabulary Grade Levels Test (Busan Metropolitan City Office of Education, 2009), which is designed to measure the receptive vocabulary knowledge of learners in L2. For the purpose of the current study, 327 participants at the elementary school participated in the study and were asked to take two different vocabulary tests. Namely, a Vocabulary Size Test (Nation, 2001) and a Vocabulary Grade Levels Test. The data were analyzed using correlation in order to discover the relationship between these two types of tests. Following this, the Rasch analysis was conducted to examine the reliability and validity of the measurement in question. The data analysis showed that both grade separation reliability and item separation reliability were high, indicating that the Vocabulary Grade Levels Test well discriminates learners with a wide range of proficiency levels. The findings of the study are discussed, along with further improvements in order to ascertain the validity of this particular vocabulary test.

FACES II & III do not capture the high extremes of the dimension and are linear rather than curvilinear measure. FACES IV is the latest revision of FACES series and can capture two extreme dimension of Circumplex Model. The purpose of this study is to examine reliability and validity of reconstructed FACES using by FACES II, III, IV. Factor analysis showed that Cohesion and Adaptability consisted 3 factors (disengaged, connected, emmeshed/rigid, flexble, chaotic) Extremes on each dimension conceptually were opposite and they were uncorrelated with each other. FACES effectively predicted family function. Reliability coefficients of subscales ranged from 61~85 Reconstructed FACES had good internal consistency and construct and criterion related validity.

The purposes of this study were to compare the reliability and validity of an 88-item version of the Gross Motor Function Measure (GMFM-88) and a 66-item version of GMFM (GMFM-66) in children with cerebral palsy (CP). The GMFM was completed in 154 children with CP (age range = 6~12). The internal consistency of the GMFM was calculated by Cronbach's ${\alpha}$ for judging reliability. The reliability of GMFM-88 and GMFM-66 were both above .99. The validity of measurement obtained by the GMFM was assessed by examining the unidimensionality of items and by comparing Gross Motor Function Classification System (GMFCS) levels with tests of the GMFM. Both the GMFM-88 and GMFM-66 were satisfied with unidimensionality. Discriminant validity was demonstrated on significant decreases in scores with increasing GMFCS levels in both measurements. However, GMFM-66 was a more sensitive discriminant in GMFCS level 1 and level 2 and in level 2 and level 4. This study reported a comparison of the reliability and validity of GMFM-88 and GMFM-66. The results of this study have implications for the information on the psychometric properties of two versions of GMFCS. This information will be useful for the selection of tools in clinics.

Purpose: The purpose of this study was to develop a new version of Spirituality Assessment Scale (N-SAS) and verify its reliability and validity. Methods: The total of 59 preliminary items for the N-SAS were selected through a literature review, two rounds of experts' content validation, cognitive interviews, and pre-tests. Verification of its reliability and validity was divided into two phases. In Phase I, questionnaires were collected from 219 adults. Reliability was tested using Cronbach's alpha, validity with item analysis, and exploratory factor analysis. In Phase II, questionnaires developed based on the results of Phase I were collected from 225 adults. Reliability was tested using Cronbach's alpha, validity with confirmatory factor analysis, and criterion validity. Results: The final version of the N-SAS comprised two dimensions (vertical and horizontal), four domains (relationship with God; meaning of life and self-integration; self-transcendence; and relationship with others, neighborhoods, and nature), and 44 items were identified. Total Cronbach's α was .97; those of each subscale ranged from .79 to .98. N-SAS scores were positively correlated with the scores of Howden's Spiritual Assessment Scale (r=.81, p<.001). Conclusion: Findings suggest that the N-SAS can be used to measure spirituality in adults. The use of N-SAS is expected to facilitate perceiving patient's spiritual needs and providing spiritual care.

Purpose: The purpose of this study is to provide researchers with a simplified approach to undertaking exploratory factor analysis for the assessment of construct validity. Methods: All articles published in 2010, 2011, and 2012 in Journal of Korean Academy of Nursing were reviewed and other relevant books and articles were chosen for the review. Results: In this paper, the following were discussed: preliminary analysis process of exploratory factor analysis to examine the sample size, distribution of measured variables, correlation coefficient, and results of KMO measure and Bartlett's test of sphericity. In addition, other areas to be considered in using factor analysis are discussed, including determination of the number of factors, the choice of rotation method or extraction method of the factor structure, and the interpretation of the factor loadings and explained variance. Conclusion: Content validity is the degree to which elements of an assessment instrument are relevant to and representative of the targeted construct for a particular assessment purpose. This measurement is difficult and challenging and takes a lot of time. Factor analysis is considered one of the strongest approaches to establishing construct validity and is the most commonly used method for establishing construct validity measured by an instrument.

Purpose: This study aimed to develop a scale to measure hospital nurses' silence behavior and examine its validity and reliability. Methods: A total of 52 preliminary items on hospital nurses' silence behavior were selected using a content validity test by seven experts on 53 candidate items derived from a literature review and in-depth interviews with 14 nurses. A total of 405 hospital nurses participated in a psychometric testing. Data analysis comprised item analysis, exploratory and confirmatory factor analyses, and convergent and discriminant validity tests. Pearson's correlation coefficient was used for assessing concurrent validity, and Cronbach's alpha was used for the reliability test. Results: The final scale consisted of nine factors with 31 items, exhibiting acceptable model fit indices, convergent validity, and discriminant validity. The score of the entire scale was positively correlated with the 'Organizational Silence Scale (OSS)-the issues on which nurses remain silent' (r = .60, p < .001) and 'OSS-the reasons why nurses remain silent' (r = .68, p < .001). Cronbach's α of the scale was .92, and α of each subscale ranged from .71 to .90. Conclusion: The Hospital Nurses' Silence Behavior Scale is a useful tool for assessing multifaceted silence behavior among nurses. It can provide basic data for developing better communication strategies among nurses and other hospital staff.

Purpose: This study was conducted to test the reliability and validity of Family Burden Questionnaire. Method: The subjects were 156 caregivers of children with acute or chronic disease. To test the reliability, internal consistency using Cronbach's α coefficient was analyzed, and factor analysis, known-group technique, and concurrent validity were utilized for validity test. Result: Cronbach's α coefficient of the tool was .89. Six factors were identified and explained 58.7% of the total variance. Through analysis using known-group technique, the difference of family burden between acute and chronic disease groups was statistically significant(t= -4.09, p<.001). Correlations with mood state, other family burden score by Family Burden Interview Schedule, quality of life, and health symptoms were also relatively high and statistically significant. Conclusion: Family Burden Questionnaire showed a relatively high validity and reliability to measure the burden of caregivers caring patients with various chronic conditions in Korea. For the further study, it may be reconsidered to identify the factor structure of the Family Burden Questionnaire with the various subjects from different age groups.
